Hi John, I first tried the three wires as per tom judge page, then all of them as per the Russian page. Still no luck. Currently I am reading up on serial communication on http://en.wikibooks.org/wiki/Serial_Programming
I think I may have to write a little java app to see whats wrong with the cable. I can find any message on /var/log/message or /var/log/syslog so its a bit difficult to see if its just a poor soldering job or I am doing something else wrong. May be the long way round but it holidays so got time to mess around with this stuff. Any pointers appreciated, regards Mark > [email protected] wrote: >> [email protected] wrote: >>> mxc wrote: >>>> Hi all, >>>> >>>> I am using this tutorial >>>> http://www.tomjudge.com/index.php/SS4000-E/Serial_Cable for the pin >>>> mappings >>>> for my serial cable.
